Silicon shows higher covalency than carbon why

1.	Silicon shows higher covalency than carbon why
Answer» This is bcoz of absence of d- orbitals in the valence shell of carbon and presence of 3d-orbital in valence shell of silicon.Since silicon has vacant 3d orbital,it can accept electrons from electron donating species<br>Because catenation occurs most readilyin carbon which forms covalent bonds with other carbon atoms to form longer chains and structures. This is the reason for the vast number of organic compound in nature
